Volvo - S60 :: Runs Rough - CEL On - Smooth When AC Is Off
basically it runs rough and makes noise when AC is on. While it may not be perfect when off, it certainly is quieter. Check engine light just came on.
View 5 RepliesFord Ranger / B-Series :: 1994 - Idles Rough / Stalls When Cold But Runs Great When Warm
I have a huge problem. My 94 ranger 2.3L 5 speed manual transmission, has problems with idoling while it's cold, has no power going uphill and stalls when I slow down to stop. This is all after putting a new motor in. The old one was running ok with 310,000 but lagging bad. I figured with the driving I do, a new motor wouldn't be a bad thing. Boy, was I wrong. It has been a nightmare. But once the truck is up to operating temperature, it runs so smooth you wouldn't think there was a problem. But let it cool off, restart, and boom! There it is. We have changed so many parts and sensors with absolutely no change to the original problem. It's very frustrating. I just can't let this problem win. I will figure it out.

My 2004 Lincoln navigator is very rough at idle but runs smooth when I give it gas. Someone said my VCT may be stuck or bad. I looked at Youtube videos of VCT replacement but in all the videos the VCT's are up front in the valve covers. On the Navigator they aren't there. Where the heck they might be located?

I have a 2001 7.3 with 259,000 miles. It does not get too cold here, however over the past few winters when the temp is below 50 at night the first minute or two of running out of the neighborhood is tough going unless I let it heat up. It has been getting worse over the past few years and now if its even 55 or 60 I need to let it heat up. Glow plugs? Injectors?

I'm working on my sons 1985 Celica GT 22RE. He was having problems with it running rough.
I've isolated it down to the number 1 cylinder being starved on warm starts. If you cold start it the problem does not occur but if you let it sit warm for 15 minutes it will fire up but nothing from number one cylinder. Lots of spark but no firing. So I'm going to tear down the EFI and move the injector to see if the problem follows it. Will probably see if I'm getting any voltage to the injector while rough before tearing down.
I can't find anything about an injector not working once warm so I'm thinking it may be an ECU problem.

2004 F250 V10, runs good until it warms up whether it's hot or cold outside. While on freeway, it really shakes while cruising, but of you get in the gas enough for a kick down, seems to be pretty smooth. I've changed the coils, and 9 plugs (one wouldn't budge, but the others I took out looked fine) to no effect. Where else should I look? Also, no CEL, and no codes, which seems odd as bad as it feels...
View 11 RepliesFort - ZX2 :: 1998 - Hard To Start And Runs Rough Through First Acceleration
I'm having a weird issue with my 1998 Ford ZX2. The car is very hard to start when cold and it runs extremely rough, but only through my first acceleration under load. In other words, I can rev the engine a few times while in neutral, and it will run very rough, and once I start driving, it runs really rough through my first acceleration, but then it smooths out and runs fine from then on until I stop it and let it call off for 30 minutes or more. If I restart it within 30 minutes or so, everything is fine, but any longer that that and the problem reappears.
View 3 RepliesFord 6.0L Power Stroke Diesel :: 2006 F450 - Runs Poorly When Cold / Better Once Warm
2006 F450 6.0 that I've owned since new. It has had 2 injectors replaced previously, EGR cooler with BPD, and a few other problem parts. As it is getting older, I have recently noticed it runs like absolute dog crap when it is cold. It can't even reasonably accelerate onto the hwy when cold. Once it is up to operating temp, it runs better. It still does not pull like it did when it was new and under 50k miles...but it is at least driveable once warm. I need to do some heavy trailer towing soon and need to get this thing back to accelerating good. What should I be looking at first for the horrible running condition when cold?

View 10 RepliesPassat (B6) :: V6 Runs Rough For 1 - 2 Minutes At Startup When Cold
My V6 3.2l runs very rough for 1-2 minutes at startup when cold i.e. the first startup of the day, or after it has not been driven for several hours. Is this normal? I understand this might be something to do with the 'anti-knocking' feature. But I only use RON 98. Also I can here something like a tappet sticking when idle all the time. Is this normal, is it just a noisy engine design? The car has only done 1800kms.

I have a 2005 Chevy Equinox with 73K miles. When I first start it up morning the car runs rough for about a minute or two and then smooths out. I took it to a mechanic who said there was oil on one of the plugs and to get rid of the car. I tried another mechanic on Craigslist and he replaced the upper plenum gaskets. It ran better for about a day or two and now the problem has resurfaced.
View 2 RepliesLS / MKZ :: 2002 Lincoln Idles Rough On Cold Mornings But Runs Fine
The car idles rough on cold mornings but runs fine. It will stall while idling but starts back easily. I am getting a 1131 and a 1151 code with my scanner along with 0300 and lean bank 1 codes. I started having these problems after I had to remove the upper intake to replace coil packs. I was getting egr code and had an egr port completely block off but cleaned that out and no longer get the egr codes. Spraying carb cleaner around the engine I get a very slight bump in rpm around a couple of the intake ports could that be my problem or should I look deeper?
View 5 RepliesFord F-150 (2004-2008) :: Runs Rough And Idles Poorly Only When Cold
I recently replaced the plugs cuz I had a rough idle all the time. During plug change when I discovered they had already been changed I found one that had a burned off electrode. Does this mean a lean condition exists?
After plug change it runs smoothly but only after 10 min warmup in our canadian winters. I can drive it when its not warm but seems to have less than full power and idles very badly after driving w/o proper warmup.
Next I changed fuel filter and checked fpdm, it was a little rusty but not bad so i just mounted it 1/4 off steel to prevent further rusting.
Since then I have installed a programmer [diablosport] but found no codes since i had battery disconnected for filter change. no new codes in last few weeks since.
So do I have a lean running cylinder causing this poor cold idle or a rich cylinder? It must be a clogged or dripping fuel injector right?

View 9 RepliesFord Ranger / B-Series :: Runs Rough For About A Minute After Engine Started When Cold
This has been an ongoing issue for about a month. When I start the engine after it has been sitting and is cold it runs ruff for about a minute then smooths out and runs fine. I pulled a P0304 code (cyl.4 missfire) but I do not get a CEL.
I checked the plugs and they were ok but I changed them and the wires anyway as it just turned 50k and the plugs were original. I could live with a little cold ruff idle but the code throwing bothers me. The truck is a 2000 xlt 4x with auto trans. and 4.0 engine. This is my second 4.0 ranger but I have only had it for about 6 months.
Touareg :: 2006 - Runs Rough After Cold Winter Starting / Choke Stuck Closed
I have had my 06 for 4 months now. I started to get a cold running problem now that the temperature is falling below 40. When I start it in the morning I wait till the idle comes down before driving. I start driving and it runs rough as if it had a choke stuck closed. I spoke with the dealer and he told me to run lower octane in the winter. That has not worked.
View 7 RepliesFord 7.3L Power Stroke (1999-2003) :: 2002 F250 Runs Rough When Cold
I have my 2002 Ford F250 Powerstroke. 175,000 original miles by me and only me. SCT, MBRP, Howes or Stanandyne almost always. Runs like new. It starts rough if I don't plug it in. Even on 50 degree days. Then it levels off and runs perfectly. If I plug the truck in I can drive off immediately with perfect operation of motor. I just went 1500 miles. Pulling a car hauler with car. NP at all.
New Glow Plugs, GPR "Yes it works", IPR, New Harness, Buzz Test shows it's fine, New #8 injector last year, New O rings HPOP. My buddy who is a PStroke guy said this trucks runs too perfect for it to be injectors. He recommends seals for the injectors. What does this mean. Or what else can it be. Where should I start.
